This invention relates to roller bearings and has for its object aroller bearing or cage construction therefor, which is particularlysimple, economical in construction on a production basis and highlyefficient in use.

The invention consists in the novel features and in the combinations andconstructions hereinafter set forth and claimed.,

In describing this invention, reference is had to the accompanyingdrawing in which like characters designate corresponding parts in allthe views.

Figures 1 and 2 are, respectively, end and side elevations of the rollerbearing.

Figure 3 is a plan view of the blank of the cylinder wall.

Fignre 4 is an inner face view of one of the heads.

Figure 5 is a fragmentary sectional View on line 5-5, Figure 1.

The cage of the bearing comprises heads l and a cylindrical wall 2, thecage being formed With raceways for receiving axles at the ends of therollers and the cylindrical Wall with slots terminating short of theheads and through which the rollers project, the strips between theslots forming spacers for the rollers and the rollers having redncedaxles in the raceways.

The inventon lies in the formation and assembly of the heads andcylindrical wall.

Preferably, both heads are alike in con-v struction and secured in thesame way to the cylindrical wall.

Each head l is an annular plate formed up of sheet metal. It is formedwith rectangular spaced notches 3 in its peripheral edge and With anannular inwardly extending flange 4 at its inner edge.

The cylindrical wall 8 is forined from a sheet metal blank rolled intocylindrical form.

5 designate the slots in the wall 2. 6 are the roller spacing stripsbetween the slots, and 7 the marginal side strips of the Wall 3 leftafter the slots 5 are formed. The marginal strips 7 are formed withtongues 8 complemental to the notches 'and secured therein, preferablyby spot welding. The marginal strips, the edges of which abut 1930,v srmNa. 448,860; o

against the heads together with the flanges l andlinterposed portions ofthe heads provide raceways 9 for the reduced ends or axles 10 of therollers 6. i

The rollers 6 are of sufiicient diameter to project beyond the peripheryof the Cage and inwardly beyond inner circles of the heads in ordertoroll on the inner surface of a bearing or raceway and on the peripheryof a shaft or other rotating part journalled in the bearing.

Preferably, the outer faces of the tongues 8, the spacing strips 5 andside margins of the cylindrical wall are fiush with the peripheries ofthe heads. Owing to the construction and assembly of the heads and thecylindrical wall, the bearing is extremely simple and economical tomannfacture in quantities and is highly efficient and durable in use. f

VVhat we claim is: I

1. A roller bearing comprising a cage consisting of opposing annularheads, each having spaced apart notches in its peripheral edge and aninturned annular flange at its inner edge and a cylindrical wall betweenthe heads, said wall having transverse spaced apart slots terminatingshort of the side edges of said wall, the side margins of said wallhaving spaced aparttongues seating and se-i cured in the notches, thetongnes projecting from the end of the cylindrical wall and flush`therewith and the periphery of the cylindrical wall being finsh with theedges of the heads in which the notches are formed, the`` portions ofthe side margins between the notches abutting against the Vheads betweenthe notches and together with said flanges and the portions of the headsbetween the flanges and the tongues forming raceways i and rollersprojecting through and extending into said slots and having axles attheir ends in the raceways.

2. A roller bearing comprising a cage consisting of opposing heads and acylindrical 9 wall between the heads, the wall having slots terminatingshort of the heads, the heads and the cylindrical wall forming raceways,rollers projectino' through the slots and having p aXles at their endsin the raceways, one of' the heads consisting of an annular plate havingspaced apart notches in its peripheral edge and an inturned fiange atits inner edge and the cylndrical Wall having tongues seeured in thenotches, the tongues projecting from the end of the cylindrical Wall andflnsh therewith and the periphery of the cylindrieal Wall being flushwith the edges of Vthe heads in which the notches are formed,

the flange and the contiguous portion of the head together With the partof the cylindrical Wall adjacent the head being so forined With saidflange forming one of the raceways. In testmony Whereof, We havehereunto signed our names, at S-yracnse, in the county of Onondaga, andState of New York, this 10th day of April, 1930.
